Abstract
A computational model of human belief revision, UECHO (Uncertainty-aware Explanatory Coherence by Harmony Optimization), has been recreated as a Java package in such a way to maximise flexibility of choice between implementations of various key internal algorithmic aspects. The original algorithms were analysed and several deficiencies, errors and weaknesses identified and corrected. The original comparison with human subjects’ belief revision patterns in a specific experimental context is recreated, and the improved algorithms presented alongside. The classes could serve as a basis for further exploration of possible constructive simulation of human belief revision in a military context conducive to fratricide. This work was conducted for the Combat ID project, which aimed at identifying the critical attributes that systems such as Blue Force Tracking (BFT) need to have in order to reduce fratricide incidence as much as possible without affecting the operational effectiveness of the Land Forces unduly.
